Step 2: Arduino Side – Hardware

I provide the step-by-step cabling: 1• empty board 2• power and I2C connections between Arduino and logic level connector 3• power connections between colour sensor and logic level convertor and 5V for the built-in LED 4• I2C connections between colour sensor and logic level convertor 5• digital connections between Arduino and opto-isolator 6• cables from opto-isolator to the fischertechnik TX controller
